IMPROVEMENT IN SHIFTING GEARINGS. v

Speciiication forming part of Letters Patent No. 158,092, dated December 22, 1874; application filed November 27, 1874.

To all whom 'it may concern:

Be it known that I, MARTIN KQLP, of Elizabethtown, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Shifting the Gear in Blowing Machines, of Which the following is a specification This improvement in blowing-machines for blacksmths consists in the facility by which the driving-Wheel can be shifted from one side of the machine to the other, so as to adapt it to the hand of the operator, or not to crowd him when an assistant is employed to turn the sain e, by shiftin g the wheel onto the other side. v

The accompanying drawings with the letters of reference marked thereon, and a brief description, Will enable any one skilled in the art to make and use the same, in Which- Figurel shows the arrangement of the bearings and the gear. Fig. 2 is a front elevation with all its parts .in place.

The standard A on a suitable base is provided with a cross-piece, B B, and side braces b. This cross-piece is joined on each side to a semicircular guide, B, forming the head of the standard. Through the center of the crossfor the bea-ring of the driving-Wheel G, and

crank-handle L. This shiftingarm Gis provided with a clamp-hook, E, made so as to embrace the semicircular plate or head B, and slide over it from one side to the other, when relaxed from the binding-nut D, on the screwend of the hook E, which also holds it in place. Thus the shifting-arm carries the driving- Wheel G with it, so as to be in gear With the I claim no novelty in the gearing or fan,

separately7 considered, the object being to overcome an objection to similar blowing-machines which have no such shifting device; therefore What I claim as my improvement is- The semicircnlar gudehead B on the crossarm B B, shifting arm and bearing C H, clampY hook E with its binding-nut D, the Whole arranged and operated substantially as and for the purpose specified.
